LADY-016 - The Secret of the Girls' Academy, The Depraved Lessons of an Anal-Obsessed Teacher

As Yuri-san mentioned, the rating really depends on whether or not you're into anal play. Personally, I find messing with a dirty anus to be repulsive. The actresses are just as gross and unattractive as the anal scenes themselves. It's an old production, so the video quality is poor and hard to watch. Even for a fan of lesbian content, I can't give this a good rating.
